To all whom it may concern Be it known that l, DAVID W. HAwKs- WORTH, a citizen of the United States of America, residing at Detroit, in the county of Wayne and "State of Michigan, have invented certainnew and useful Improvements in Car-Roofs, of which the following is a speciiication, reference being had therein to the accompanying drawings.

The invention relates to car roofs of the all-steel type and is particularly adapted for use in car roofs of that type in which the ridge purlin is arranged lon top of the ycarlines and in which the rooting sheets are weather-proofed by carline and ridge caps, which are in turn weather;prooted by junction caps held in' place by bolts having heads extending thereabove. One object of the invention is to obtain a construction in which a truss is formed for the central portions of the carlines. Another object of the invention is to obtain a construction in which the running-board saddle forms this truss. A further object of the invention is to ob.- tain a construction forming a truss for the carlines which extends substantially from eaves to eaves of the car roof. Still another object of the invention is to obtain a construction in which the carline caps and the means for securing the running-board saddles to the carlines can be assembled and secured together prior to their assembly in the car roof. A still further object of the invention is to obtain a construction in which the heads of the bolts extending above the junction caps are weather-proofed by the running-board saddle so that any water falling upon the running board saddle will be discharged without the confines of the bolt heads. Stillother objects of the invention reside in the novel arran ements and combinations of parts as more ully hereinafter set forth.

In the drawings: i

vFigure 1 is a perspective View of a car r'oof embodying my invention, with parts broken away;

Fig. 2 is a transverse sectional View 4therethrough;

Fig. 3 is a plan View of the run-ning board saddle; l

Fig. 4 is a sectional View on'the line L -4 of Fig. 3;

Fig. 5 is a sectional view, showing a modipied construction of saddle;

Fig. 6 is a perspective view, with parts broken away, of a portion of the car roof;

Fig. 7 is a transverse sectional view through a car roof;

Fig. 8 is av diagrammatic View of the car roof, showing the trussing arrangement fr the carlines.

A are the carlines, B is the ridge purlin arranged upon the carlines centrally thereof, and C are the relativel -movable roofing sheets having the upstanding flanges D at their sides which'arev weather-proofed by the carline caps E and also provided with the upstanding flanges F at the ridge which are weatherLproofed ,by the ridge ca .ps G. H are the junction caps fitting upon the adjacent ends ofthe carline and .ridge caps E and G' respectively for weather-prooing the car roof, and l are the bolts for securing the junction caps to the carlines, the bolts ein tending centrally through the ridge purlin and having the exposed heads I extend above the junction caps.

J are the running board saddles arranged in the planes of the carline caps and rigidly connected near opposite ends to the carlines,

A by the Z-shaped brackets K formed of pressed sheet metal and having the reinforcing side flanges K. The shoulderjbolts L extend at right angles tothe base anges of the brackets K and the inclined shoulders A upon the carlines A and are engaged at their lower ends by the nuts L to secure the bracketsrigidly in place.y The up er shoulders L2 upon the shoulder bolts t tightly against the carline caps E and maintain these caps and also the brackets I in fixed spaced relation relative-to the carlinesA. With this construction each running board saddle forms a truss for the central portion of the carlines inasmuch as its ends are rigidly connected to the carlines at spaced points upon opposite sides of the ridge urlin.

With the above construction the assembly of the car roof is also greatly facilitated since the carline caps E, the brackets K, and the bolts L can be assembled andsecured permanently together prior to the complete assembly of the car roof. The vcarline caps E are ri idly secured near the eaves to the carlines by means of thebolts E which are preferably also permanently secured to the carline caps. The ends ofthe carline caps at the ridge rest upon the ridge purlin B. Due to the fact that the lcarline caps are rigidly secured to the carnear the eaves on opposite sides of the car the carline is not inclined,y shoulders.

roof.

'The saddles J arev pressed from sheetmetal to provide plain surface portions for supporting the running-boards and to provide weather-proofing means `for the exposed heads I of the junction cap bolts I.y In detail, each saddle has the horizontally-extending portion" M for supporting the running boards N and is also provided with the depressed transversely-extending channels O which provide suicient space beneath the running-boards for the heads J 2 of the bolts J securing the saddle to thel brackets K. Extending longitudinally and centrally inward from the depressed channels 0 are the depending ribs P, which are inclined downwardly toward the center and at their inner ends inclined sharply downward and terminate in the concave-convex cap portion Q, adapted to surround and embrace the exposed head I of the bolt I to weather proof the same. The depending ribs P are formed by striking out the longitudinal central portions of the saddle, which also forms the elongated openin s P ntermediatethese depending ribs. ith this arrangement the running-board saddle is greatly reinforced and, furthermore, `any moisture, cinders, or other materials which would collect upon the saddles are free to pass through the openings and of the Saddles.

The cap portion Q of the running-board saddles has the sides Q extending down about the exposed head I of the junction cap bolt to a point therebelow so that the exposed head is `embraced thereby and weather-proofed andany moisture dropping upon the cap portionl will be discharged therefrom without the confines of the head.

As shown in Figs. 1, 2 and 6 the inclined shoulders A have a fiat circularl face and are located longitudinallyI centrally of the carline. pressed in the carline and have one edge located within the plane of the outer face thereof -and the opposite edge located outsidei of the plane.
